What would be a right style for music of this saga? Has anyone composed anything? I know that for some book trilogies fans have created many soundtracks. I'd like to listen original music for this fine story...
It depends. There are long exposition parts, for which some light strings are good. Battle sequences demand drums and horns.
I recently watched the original Star Wars movies for the first time in many years. I remembered them as masterpieces of thrilling music tied to good action sequences, but to be honest it really seemed amateurish. So I don't know. You could put anything with it.
I prefer Jean Michael Jarre's Equinoxe while reading, myself.
I think the main saga theme should be called "Aurora CV-01", with drums and wind metals... Epic.
